4 管脚接口

Pin Interface

注意:模块只能 3.3V 供电,5V 供电会烧毁芯片,切记切记!

Attention: The model only apply to 3.3V power supply

正面:

Frontside:

 GPIO12 GPIO13 GPIO14 GPIO4 GPIO5 GPIO15


背面:

Backside:

 GPIO16 GPIO0 GND TX RX VCC


默认烧写的固件为 5 路继电器控制固件,使用的 GPIO 资源为: The default firmware is 5 channel relay control firmware, GPIO source:

1. GPIO13(D4) control the 1st relay
2. GPIO12(D5) control the 2nd relay (pull up)
3. GPIO14(D6) control the 3rd relay
4. GPIO16(D7) control the 4th relay
5. GPIO4 (D8) control the 5th relay


6 路继电器控制固件,第 6 路为: GPIO5 (D9) control the 6th relay

6 channel relay control firmware, the 6th channel is: GPIO5 (D9) control the 6th relay


应用如需外接 I2C 口的传感器、OLED 屏等,可将 GPIO4 (D8) 和 GPIO5 (D9) 作为 I2C 之 SCL 和 SDA,参考示例:

If need to connect sensor with I2C interface, OLED screen etc...GPIO4(D8) and GPIO5(D9) can work as SCL & SDA of I2C, for example:


这样即便 GPIO4 和 GPIO5 用作 I2C,依然有 GPIO12, GPIO13, GPIO14, GPIO15, GPIO16, GPIO0 用作继电器控制

Although GPIO4 and GPIO5 act as I2C, GPIO12, GPIO13, GPIO14, GPIO15, GPIO16, GPIO0 still work as relay controller

9 固件烧写

Firmware Download

模块默认烧写的是微信控制 5 路继电器的固件,可自行刷写微信控制 6 路继电器的固件

Default firmware that the model upload is WeChat control 5 relay, 6 relay firmware can be write by your own

模块自带 Bootloader,可直接通过串口刷写固件。

Bootloader built in, the firmware can be uploaded through the serial port directly

GPIO0 拉高是正常启动;拉低后再上电,模块会自动进入刷机模式

GPIO0 start up is normal; Pull down and then power up the module will automatically enter upgrade mode

9.1 准备工具

Tools Preparation

模块设计时把编程刷机的接口都放在在背面,用一个顶针接上杜邦线,连上 USB 转 TTL 板,就能刷写固件

Both programming and upgrading Interface were in the back of model. Use a thimble on Dupont line, connected to the USB switch TTL Panel, firmware can be upgrade then.

准备一个 5 pin 的顶针,此物某宝有售,烧录探针2.54 5P烧录工具

One 5pin thimble, order linkage: 烧录探针2.54 5P烧录工具

5pin.jpg


准备一个 USB 转串口板,此处我们使用一个 FT232RL USB 转串口板,此物某宝有售:FT232RL USB 转串口板

One USB switch serial port board, we used FT232RL, order linkage: FT232RL USB 转串口板

Ft232.jpg


如下接线:

Wiring as below:

  • USB_GND ------> NODEC_GPIO0
  • USB_GND -----> NODEC_GND
  • USB_RXD -----> NODEC_TX
  • USB_TXD -----> NODEC_RX


以上接好后,最后 USB_VCC3.3 -----> NODEC_VCC 通电开机,即进入刷机模式

Last but not least, USB_VCC3.3 -----> NODEC_VCC power on, then enter upgrade mode



9.2 准备固件

获取 noduino-sdk:

Obtain noduino-sdk

$ git clone --recursive git://github.com/icamgo/noduino-sdk.git noduino-sdk


生成 toolchain (you need Python 2.7):

Generate toolchain (you need Python 2.7)

$ cd noduino-sdk/toolchain
$ ./gen.py

编译:

Translate & Edit:

$ cd ../sketch/ctrl6relay
$ make


各平台下,Noduino SDK 使用,更多参考:

Noduino SDK usage under different platform please refer to:



9.3 刷写固件

还是在 sketch/ctrl5relay 目录下,直接 make flash:

$ make produce

即可上传固件。不同平台下,你的串口设备号可能不一样,确认一下你的串口设备,比如在 Windows 下 FT232RL 板可能被识别为 COM3 (设备管理器里查看),则:

$ make produce ESPPORT=COM3

即可



10 常见问题

10.1 射频性能

出厂测试,保证家用环境下 WiFi 穿一堵墙,配网和控制可正常使用

如发现配网多次失败、经常掉线类似问题,可先用示波器确认电源纹波:

一般情形下,发送 11N MCS7 的包,电源纹波必须 < 80 mV。发送 11B 包时,电源纹波必须 < 120 mV
